Mexican authorities seized 120 kilograms of fentanyl pills—equivalent to 4 million doses—in Mexicali, Baja California, at a property linked to “Los Rusos” (The Russians). This group is identified as an operational arm of the Sinaloa Cartel, specifically serving the faction led by Ismael Zambada Sicairos, known as “El Mayito Flaco.” The seizure also included a firearm and vehicles; the operation resulted from information sharing with the U.S. Drug Enforcement Administration (DEA) combined with intelligence work by Mexican agencies, according to Omar García Harfuch, head of the Secretariat of Security and Citizen Protection (SSPC).
The key detail of the operation was the sheer volume of the seized narcotics: 120 kilograms of fentanyl pills, an amount authorities estimated to represent over 4 million doses. The raid took place at a property connected to “Los Rusos,” a group primarily active in Mexicali and the Mexicali Valley.
Omar García Harfuch, the SSPC chief, reported that personnel from the Attorney General’s Office (FGR), the Ministry of Defense (Sedena), the Navy (Semar), and state authorities participated in the deployment. The operation was carried out in Mexicali following data cross-referencing with the U.S. anti-drug agency and investigative work conducted by the Security Cabinet.
García Harfuch detailed that the fentanyl pills, along with a firearm and several vehicles, were found at the site. The intervention struck a structure identified by authorities as an operational and hit-squad arm of the Sinaloa Cartel in that border region.
The official maintained that international cooperation—combined with the investigative and operational capabilities of Mexican institutions—made it possible to turn intelligence into concrete results against criminal organizations and their logistics networks. He delivered this message while in Buenos Aires, Argentina, where he was attending the 40th International Drug Enforcement Conference (IDEC).
